Too/ZZ whom it may concern? Be it known that I, Jo'HNW. GARMACK, a citizen of the United States,'residing at Dyersburg, in the county of Dyer and State of Tennessee, have invented a new and useful Hayi Press, of which Vthe `folldwingis a specification. l f

My invention relates topower balingpresses, especially designed for 'the baling of hay, although capable of use for baling other materials. y

The object is to generally improve the construction of such presses, with a view to increasing the strength and capacity thereof and decreasing the amount of power necessary to operate them.

With this object in view my invention consists in the improved construction, arrangement, and combination ofthe parts ofaJ press,

secutively of lesser radii and the teeth of the plunger-rack of consecutively-greater length. The effect of this arrangement is to move the plunger forward at a speed gradually lessening and with a power gradually increasing, the power being required to increase as the hay becomes more compact and solid. The two long teeth assure the engagement of the pinion and rack. As the rollers 87 pass into the throats of the' teeth they raise the valvestems 44 and permit oil to pass down through the openings from the oil-reservoir 83 to lubricate the rollers 87. The machinery should not be stopped with any of the rollers in contact with a valve-stem, as this would permit leakage of oil.

To begin baling with an4 empty press we will let it be supposed that the parts are in the following positions-viz., the plunger at about the middle of its forward stroke, the

per and on their upstroke, the condenserwalls in their open positions, and the condenser-head contracted. At this juncture will deposit a charge of hay previously placed on the chute 113 into the condenser. In the continued operation of the press the plunger continues its forward motion ,the-feeder its upstroke, andthe condenser-head begins its forward movement, resulting in the inward movement of the condenser side walls, all of these parts completing these strokes at the same At the en d of these strokes the movement changes, the condenser-head moving forward at a spe'ed to require a half-revolution of vduring the return movement of the main plunger, owing partly to the fact that the main shaft has only made one-seventh of a revolution and partly tothe fact that both movements of the condenser-head are slowest at their beginning and ending, these movev ments being made by a crank and pitman,

which at the exact moments of ending of the forward and backward strokes passes its two dead-centers, the head being virtually still g has begun its forward movement.

for about one-sixth of a revolution at each dead-center. The next forward movement ,y of the main plunger now begins, and as it takes six-sevenths of a revolution of the main shaft to complete this movement the con- [denser-head during the movement completes i, its forward movement and makes its entire next return movement bringing the main 5 plunger to the end of its forward movement, l at the same time the return of the condenserhead is completed and, as before stated, the feeder Ais at the end of its upward movement. At the point in the return movement ofthe l main plunger where, as before stated, a charge of hay was introduced into the condenser-hopper a second charge is nowintroduced and the x movements continue, as last stated, to the end 1 of the return of the plunger;

Each charge of hay placed in the condenser-hopper is-pressed by the feeder into that part of the main cham- 1 ber immediately below the hopper, which I designate as the charge-chamber, in advance of the plunger-head,which at the time of the receipt of the hay in the charge-chamber Each forward movement of the main plunger presses the last charge against the precedingone,push= l ing them into the baling-chamber. l starting to bale hay with an empty press these l movements are continued until the hay in the baling-chamber has attained su'liicient coml pactness, when at the point in the operation i when the plunger has moved far enough on its feeder-blades just clear of the condenser-hopforward movement to bring its shield below the slot in the top of the chamber a separatorblock on the separator-block chute is raised l to a vertical position in the slot, with its lower the operator standing on the stage-plank 114 edge resting on the plunger-shield. The separator-block remains in this position until the plunger completes its forward movement and i has moved far enough on its return to permit the block to drop into the charge-chamber. v The plunger in its next forward movement presses the charges placed in the Vhopper I against the separator and into the bale-chaml ber until a sufficient number of charges to form a. bale have been pressed forward, which will be indicated by the ringing of a suitable alarmbell, which I have not shown, and which alarm will be the signal for the operator to stand another blockin the slot. As soon as a separator-block appears in the open-work portion of the bale-chamber wires, already cut to length and twisted into a loop at one end, are passed through the spaces 63 and the groove in the separator-block, and upon the appearance of the next block the wires are inserted in its front grooves and the end secured in the loop by twisting. As the separator-block and pressed hay pass between those portions of the side sheets 3 between the slots 61 a lateral inward-tension pressure is exerted against them, so that the resistance to their passage will be sufficient to compact the succeeding charges until the first bale reaches the discharge end of the chamber, where a tension-pressure is exerted against In first' IOC IIO

its sides by the tension-plates 64, pressed inward to give any desired pressure, by means of the screws 91, operated by hand by means ofthe hand-wheels 98. The outer edges of the side sheets 3, between the slots 61, act as detents to prevent return movement of the hay and serve to assist the spring-actuated detents 95 in this function. The hay pressed under the tuckerroller 47 passes freely, owing to the free rotation of the roller in that direction, but is prevented from moving backward by the roller, which is locked against backward rotation. The movements in and out of the side walls 50 and 49 are effected by rollers 101 and 52, respectively. These rollers are mounted vertically, 101 on the outside and 52 on the inside of said walls, and are moved forward and backward in straight lines with the condenser cross-head. Their lines of movement are parallel with the sides of the frame, and the pintles of the walls 50 are set slightly within said lines, so that movement of the rolls towardthe pintles will press the walls outward, and vice versa. The motion ofthe condenser cross-head is eifected by the crank-pins 90, pitman 94, rocking arms 95, and connecting-rods 96, the points of connection of pitman 94 with rocking arms 95 being nearer the pivots of the arm than the points of connection of connecting-rods 96 therewith, the advantages due to this arrangement being to apply the power to the cross-head more nearly in the line of its movement and to lengthen the stroke of the cross-head, thereby increasing the spread of the side walls of the condenser and increasing its capacity for the reception of loose hay. The length of stroke of the cross-head may be varied by adjusting the pivotal connections of pitman 94 in the slot 95a of the rocking arm.

As'before described, the feeding mechanism is actuated from the plunger-stem by means of the cross-shaft 29, secured in the lower ends of the connecting-rod 1 5 and passing through an elongated slot ,29a in the stem. (See Fig. 20.) This permits of the movement of the shaft and stem with relation to each other, due to the yielding connection between the boxes 26, which carry the shaft andthe stem by means of clips 123 and springs 24: The connecting-rod 15 is on a vertical position when the feeder is in its highest position, and the :first part of the return movement of the plunger-stem has very little effect in moving the feeder down; but as the connecting-rod 15 is inclined away from -its vertical position by the continued movement of the stem the downward movement of the feeder is accelerated. The latter portion of the upward movement of the feeder is re` tarded correspondingly, thus giving the effect of a rest at the upper end of its strokes and allowing more time in which to feed thehay into the hopper. A. further effect of this arrangement is to cause the feeder to act as an equalizer of the strain on the power, inas- :much as the arrangement requires the application of a greater amount of power to drive the feeder down than would be necessary with more direct connections. This is due to the fact that the pull exerted upon the feedera'rm 14 by connecting-bar 15 is almost in line with the feeder-arm, thus increasing the work Acarrying the plunger-stem back with it by means of connecting-rod 107.- This movement, as before stated, is accomplished during one-seventh of a revolution of the main shaft, and at its completion the tooth 21.1 is ready to engage the tooth 22d of the plungerrack to begin the next forward stroke, during the first part of which the return-arm 41 is drawn back by the plunger-stem and the roller 86 engages the curved edge of link 43, thus preventing rattle, lost motion, or wrong engagement of teeth of the pinion and rack.
